BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofPenstemon plant, botanically known as Penstemon hartwegii andhereinafter referred to by the name ‘Barpenpeppur’.

The new Penstemon plant is a product of a planned breeding programconducted by the Inventor in Aalsmeer, The Netherlands. The objective ofthe breeding program was to create new early-flowering Penstemon plantswith attractive flower color.

The new Penstemon plant originated from a cross-pollination made by theInventor in August, 2013 in Aalsmeer, The Netherlands, of a proprietaryselection of Penstemon hartwegii identified as code number Pe-0003, notpatented, as the female, or seed, parent with a proprietary selection ofPenstemon hartwegii identified as code number Pe-0099, not patented, asthe male, or pollen, parent. The new Penstemon plant was discovered andselected by the Inventor as a single flowering plant from within theprogeny of the stated cross-pollination in a controlled environment inAalsmeer, The Netherlands in April, 2014.

Asexual reproduction of the new Penstemon plant by cuttings in acontrolled environment in Aalsmeer, The Netherlands since April, 2014has shown that the unique features of this new Penstemon plant arestable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Penstemon have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Barpenpeppur’. These characteristicsin combination distinguish ‘Barpenpeppur’ as a new and distinctPenstemon plant:

-   -   1. Upright and relatively compact plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit.    -   4. Early and freely flowering habit.    -   5. Long flowering period.    -   6. Dark red purple-colored flowers with light pink-colored        centers.    -   7. Good garden performance.

Plants of the new Penstemon differ primarily from plants of the femaleparent selection in the following characteristics:

-   -   1. Plants of the new Penstemon are more compact than plants of        the female parent selection.    -   2. Plants of the new Penstemon flower earlier than plants of the        female parent selection.

Plants of the new Penstemon differ primarily from plants of the maleparent selection in the following characteristics:

-   -   1. Plants of the new Penstemon are more compact than plants of        the male parent selection.    -   2. Plants of the new Penstemon are more freely flowering than        plants of the male parent selection.    -   3. Plants of the new Penstemon and the male parent selection        differ in flower color as plants of the male parent selection        have solid red-colored flowers.

Plants of the new Penstemon can be compared to plants of Penstemonhartwegii ‘Barpenpeppin’, disclosed in a U.S. Plant Patent applicationfiled concurrently. Plants of the new Penstemon and ‘Barpenpeppin’differ primarily in flower color as plants of ‘Barpenpeppin’ havelighter red purple-colored flowers with light pink-colored centers. Inaddition, plants of the new Penstemon are more compact than plants of‘Barpenpeppin’.

Plants of the new Penstemon can also be compared to plants of Penstemonhartwegii ‘Polaris Purple’, not patented. In side-by-side comparisons,plants of the new Penstemon and ‘Polaris Purple’ differ in the followingcharacteristics:

-   -   1. Plants of the new Penstemon are more compact than plants of        ‘Polaris Purple’.    -   2. Plants of the new Penstemon have longer leaves than plants of        ‘Polaris Purple’.    -   3. Plants of the new Penstemon flower earlier than plants of        ‘Polaris Purple’.    -   4. Plants of the new Penstemon are more freely flowering than        plants of ‘Polaris Purple’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurementsand values describe plants grown during the summer in 13-cm containersin an outdoor nursery in Aalsmeer, The Netherlands and under culturalpractices typical of commercial Penstemon production. During theproduction of the plants, day temperatures averaged 22° C. and nighttemperatures averaged 17° C. Plants were pinched one time and were threemonths old when the photograph was taken and six months old when thedescription was taken.
